Easy Questions: What is the typical depth of analysis for XPS? Describe the difference between Raman spectroscopy and FTIR. What are the benefits and pitfalls of grazing incidence angle XRD? Describe the difference between IR spectroscopy in ATR mode vs. transmission mode. What range in IR spectroscopy are OH stretches? Questions that were irrelevant to the job and my experience: Describe the chemical mechanism of photolithography? What chemical structure for a polymer would make a good mask material for photolithography?
